Fig. l is a View showing @Windshield #ving embodying my invention attached to a Windniy be swung back sot-lint ythe edge thfeeof mounted upon theeflgei'of'theWing. Fig. 4 1S a fragmentary Vertical sectional v'iewillustijating' tlieinmnei' in which the supporting rod is attaclied to the deflection plate.

Fig. 2v is'y a seotion taken iipii.j ]jlane' represented-by theline 2-2 of Fig. l, showing one of the positions*in- Whibh the Wln'dthis being due tothe s Fig)v 8 section through a olniping `bers lysfhielil are applied to theedgeefofthe and ze they iii) of functions as a lever of the'third Class in which the end engaging the pivot stud 19 is the .iulcrun'n the opposite end being the weight end, and the intermediate portion engaged by the bolt 24 being the point ot application of the iower.

Thus a clan'iping of the jaw members 20 upon the side bar 17 of the windshield frame causes a transverse shearing strain to be eX- crted by the fulcrum ends thereof, upon the stud 19, this exerting a fixed initial restraint against free rotation of said stud, additional regulated restraint ot such rotation being effect-ed by the tightening of the nut 21 as above explained. y lli/lith this type of construction the .nuts 21 do not have tobe tightened to an extent which would -be'liable to vcause a stripping of the threads. y

The manner inv which the attachment members 13 are secured to the plate 11 isshown in Y Figs. 4 and 5. These members 13 are each provided with a channel 23 somewhat wider than the thickness or' the glass plate, and are adapted to be forced over the edges y29 of the plate 11 with a layer of compressive ma terial 30 therebetween. This compressive material. may be petroleum impregnated felt or a strip for rubber. A. notch 32 is' 'formed in the edge of the plate 11 in a position corresponding to a hump 33 formed upon the bottom 34 of the channel 28, so that when the attachment members 13 are placed upon the edge of the plate 11, the material 30 will be pressed into the depression 32 by the hump 33,'thus providing an engagement il O between the member 13 and vthe plate 11 which willprevent thismember 13 from sliding along the edge of the plate. The lower end 38 of the'v rod 12 is threaded into "a boss 39fprovided upon the lower attachment member 13, and a clamping nut 40 locks the two members firmly together.

The upper end 42 of the rod 12 is adapted to slide Jfreely through an openingV 43 provided in the boss 44 which is associatedwith the upper attachment member 13, and a nut 45 and a cap 46 are provided to secure this attachment member 13 upon the upper end of the rod 12 and to adjust the attachment member 13 to its proper position relative to the length of the plate 11, so that excessive pressure will lnot be applied through the screwing down of the cap 43 upon the rod 12 and causing the breakage of the glass.

As shown in Fig. 7 of thedrawing, I provide an edged strip 47 which is adapted to be mounted upon the inneredge 48 of the plate 11 and has a. longitudinal opening 49 extending therethrough so that a thin outer wall 50 is provided, this edge strip 47 having a utility which will be hereinafter described. i f

The normal position ofl the windshield wing is shown in Fig. 2, in which the brackets 15 are illustrated in positions perpendicular to the extension ot' the windshield 51 upon which the wings are mounted with the brackets in this position. The plate 11 may be adjusted .to any desired position ot angu- 2*- larity, leaving a space 52 between the edge 48 of the wing and the closure Jrior ventila# tion.. It no ventilation is desired, or in event of rain, the arms 15 may be swung over into the position in which they are shown in tween the edges oi' the plates 55 and the side bars 17 of the windshield 51.` 'The compressibility of the strip 47 contributes to the forming of a watertight closure against the plates 55. Y l f f l The hereinbefore described 'manner of mounting the bar 12 upon' the detlector plates 11 provides for the correct spacing of the attachment members 13 and eliminates the institution of stresses within the yplate which ordinarily makes the plates susceptible to shattering by the vibrations o1e the body ofthe automobile which are encountered in ordinary driving and which are sometimes derived tromthe operation .of the motor. Also the use of ay layer of compressible material between the members 13 and the plates 11 damps the passage `oii vibrations to the plates 11 and absorbscertain of the pressure which might be brought to bear by the 'improper adjustment o the nut 45 and the cap r46. f

l claim as my invention:

1. In a vdevice of the nature disclosed, the combination of: a pair `of relatively spaced bracket arms each having near its inner end an integralvertical pivot'stud; a delector member hingedly supported on the outer f ends of said arms; and a'pair of clamps, one associated with eachrespective bracket arm, each clamp comprising two j aw members and each jaw member constituting a lever ot the third class having at one endan opening to receive the pivot stud or the associated bracket arm, the opposite end of each jaw member being formed to clamp 'against a support to which the device is to be applied; a bolt `means 'tor each clamp, each bolt means engaging the intermediate portions of the companion pair of jaw members to draw said members together to grip said support and cause an initial frictional restraint on the cooperating pivot stud; and a nut on each pivot stud fortrictionally clamping the aw members to the respective bracket arm.`

2. In a device of the nature disclosed, the combination of a supporting structure comprising a bracket arm having near its inner end an integral pivot stud; a. clamp means hingedly connected with saidstud and c0mprisng two opposed jaw members, each oonstituting a lever of the third classv and having at one end an opening to receive the pivot stud, the opposite end Jchereof being formed to clamp against a support to which the def Vice is to be applied, and means engaging the intermediate'portions of .both Jaw members to draw said members to clamping engagenut on said pivot stud for frietionally olamp-y y the jaw members to the bracket arm.

In testimony whereof, I have hereunto set my hand at Los Ange1es.Ca1ifornia, this 31st day-of July, 1922.
